FORM FOR SETTING VA'ULT LGl-TS.

Application filed July i8,

This invention relates to forms for setting vault lights, by which title is meant in this application the devices shown and described for accurately and quickly placing the lenses and their encircling trames in proper spaced positions to receive the surrounding fiirative body of cement by which the lenses and their frames are permanently held.

The object ot this invention is the production of' forms for the purpose mentioned., and which are ot' special construction and arrangement believed to enable any piece of work to be more expeditiously and conveniently performed than may be accomplished by whatsoever means employed with which this applicant is acquainted.

Of the accompanying drawings illustrating this invention, Figs. l, 2 and 3 represent top plan views of several equally preferred and used shapes of the same form. Fig. l is a sectional view showing a lens in its frame and in engagement with the torni and surr-ounded by the cement in its final position. Fig. 5 shows a lens in a modified form ot' trame. engaging the form illustrated in Q. Fig. 6 shows a section similar to Fig. 5 illustrating` a lens in another shape of frame and engaging the form illustrated in 8. 7 is a top plan view of a number ot associated hexagonal forms which are sometimes used. Otherwise these forms are the same as set out in Fig. 3.

Throughout the drawings and description the same letter is used to refer to the same part.

Consideringthe drawings, the form A in Fig. 1 has a square outline externally, and a rectangular opening a. The form A is not necessarily square in contour, but may be rectangular, such as the form a with more than a single opening. It may be stated here, that the forms while shown in this application as made of rubber. may be fashioned of any other selected material which will render the service expected of them. They may be of fibre, or of wood, or of any of' the various compositions of materials known at present. The forms are arranged evenly upon the supporting board with their edges in contact. It will be understood that the forms are removable. They may be taken away one at a time. As shown in Figs. 2, 3 and "t", it is usual in practice to have one form for each lens, each form being separately removable as stated. If the lenses are small, it is believed to be within the pur- 1924. Serial No. 7225.806.

View of this invention to seat two lenses in the form.

In Fig. 2 it will be observed that the form B has a circular opening b, and that there is an adjacent shoulder C bordered by the annular ridge c.

In Fig. 8, the form D has the circular opening Z bordered around the edge of the opening by the ridge CZ.

Considering Fig. t it will be noted that the lens E is supported by the usual board c employed in setting vault lights ot the character described, and the lower portion of the lens E is shown as passing through the opening a in the form A. The forms A are arranged upon the board c edge to edge as delineated in l. The lens E is shown as seated in a trame F, so shaped as to afford a suitable seat for the enlarged upper portion of the lens, and about the lower part of the lens which passes through the open frame F, and in contact with the rameis the clamping band The clamping band is shown as of rubber, butthe invention is in no sense confined to any particular material or form of hand. Stout composition.l fabric or even leather could be employed.` The function -ot the clamping` band is to hold the lens and frame together in proper spaced relation. It will be observed that when the lens and frame are clamped together and the lens is placed in engagement with the opening` of the form plate A, the position of the lens and frame is fixed, and after the desired number of lenses have been thus located, the cement filling G and g may be applied to finally hold the lenses in place. Thereafter, the board e is removed, and the forms A also removed to be used over again on other like work. It may be stated here that the kind ot reentorcing rods, bars or other irons constitute no part of this invention, and any method of reenforcing may be employed together' with the use of this invention.

In Fig. 5, the lens H has its lower portion resting upon the board 7a, while the frame J which encloses the lens is resting upon the form B. The lower end of the lens engages the opening Z2 in the form B, and the lower end of' the frame J engages the shoulder C ot the form adjacent to the opening as illus trated. Any number or shape of external fins y' may be provided upon the outside wall of the frame to fix the frame in the cement tilling K, in the ycustomary manner. The

lens is secured in the trame by means of the cement filling' le.

In Fig. the lens Lis shown with its lower part or month engaging the ridge (Z oi: the opening; CZ in the :torni D,which is supported by the board or boards Z and is removable with the boards as explained hereinabove. The lens frame Miso'lf the saine character as the 'traine F described in -wnnection with Fin'. fl. It is m'ade with a seat 'for the enlarged upper part ot the lens L, and around the lower portion ot the lens and in contact witl the lower surface of the trame M is the clamping hand fm having` the saine Aiinnetion and capable of being' made of any Vchosen materials as already explained. rlhe band m remains in the cement filling` N, but the forms D are removed when the cement has set. rlhe lens is secured by the filling;` n in the manner nomi-non in such structures, and while the word icen'ientis used in this description, vit will be underf'-;tood to mean any materiels employed for this purpose.

The operation of this invention is believed to have been made olea/r in the foregoing explanation. r:lhe clanipinp; band holds the lens and frame together in proper attitudes one with respect to the other. and when the forms `are arranged vupon the supi'iortinfij board, the lenses may be quickly and ac curately positioned. After the filling has suiiiciently set` and the supporting); boards removed, there is no diiiicnltv rat all found in taking off `the forms for like use in other jobs.

Having now `described this invention, and explained the manner of its operation, what I claim is l. In a Vault light setting', the combination with a removable flat support, of a plurality of flat forms carried by the said support and removable therefrom, the said 'forms beingl arranged vin contact one with another to make a covering ifor the said support, each of the said lorins having' an opening, which opening' engages a lens, the axes oit same and of the opening beine' coincident.

Q. In a vault light. setting, the combination with a removable flat support of a plurality ot flat forms carried by the said sup port, the said forms being arranged in oontact one with another to make a covering` for and removable troni the said support, each o' 'the said forms having' an opening, which opening engages and supports lenses and lens frames, the .axes of the saine and oi' the oi'ieninn` being;` coincident. y

3. ln a vault light set-ting, the combination with a lens having' .an enlarged upper portion, oian open lens frame having; a seat for the said upper portion oit the lens, the said lens having` a lower por-tion .passing through the frame. and a clamping band `arranged upon the lower portion `oi 'the lens below the iframe and in Contact with .the traine `to hold the ,lens and 'traine together.

4.-. In a Vault light setting'. the combination with a lens having an enlarged ripper portion, ot an open lens traine having a seatfor the said upper portion of the lens` the lower portinnet the lens passing' through the said frame, a clamping` band arranged upon the lower portion of vthe lens below the frame and in Contact with the `traine Ato hold the lens and traine ytogether in spaced relation` and `cement illing; securing' the 'lens in the tranie and surronndingl` the said frame and `the said 1band and the said lower portion of the lens.

In testimony whereof I aiiix .my signature.
